n a surprising turn of events, the first round of an “adversarial collaboration” between two leading theories of consciousness has ended in a qualified victory for the camp that believes consciousness arises from networks of neurons at the back of the brain. The event took place in a Greenwich Village theater in New York City, where advocates of the Integrated Information Theory (IIT) and the Global Neuronal Workspace Theory (GNWT) eagerly awaited the results.
The collaboration, funded by the Templeton World Charity Foundation (TWCF), aimed to settle the debate on how consciousness emerges within the brain. Both theories agreed on experiments to be conducted by “theory-neutral” labs, with no stake in the outcome. The judges, who were chosen to design the experiment and evaluate the results, gave more points to IIT, suggesting that consciousness is a feature of networks of neurons found at the back of the brain.
However, the opposing camp, which believes consciousness emerges within the brain’s prefrontal cortex, is not ready to concede. They argue that the experimental round had limitations and that the results of other tests in the collaboration will support the role of the prefrontal cortex. The chief architect of GNWT, Stanislas Dehaene, believes that the new findings do not confirm the specifics of IIT and that the results challenge both theories.
The collaboration also marked the end of a 25-year-old bet between cognitive neuroscientist Christof Koch and philosopher David Chalmers. Koch bet that the neural correlates of consciousness would be identified within 25 years, but the results of the collaboration showed that those correlates remain unclear. Koch graciously conceded the bet and offered Chalmers a bottle of 1978 Madeira, with five more fine reds in the wings.
The debate on consciousness has long fascinated philosophers and neuroscientists alike. The search for a working theory of consciousness is crucial for making decisions about brain-damaged patients, determining the rights of animals, and understanding the potential consciousness of artificial intelligence. The GNWT and IIT are among the most widely discussed theories of consciousness, with each camp presenting evidence to support their claims.
The collaboration aimed to address the contested evidence by designing two experiments that would test the predictions of each theory. The first experiment involved showing participants images with and without an accompanying task, while the second experiment, which is yet to be announced, will use a customized video game to isolate neural signals of conscious perception.
While IIT has gained an initial advantage in the collaboration, both camps acknowledge that the results challenge their theories. The collaboration has provided valuable insights into the nature of consciousness, but the debate is far from over. The next round of experiments, funded by TWCF, will further explore the role of the prefrontal cortex and may provide a clearer understanding of how consciousness arises in the brain.In a highly anticipated scientific showdown, two leading theories on the origins of consciousness clashed in a Greenwich Village theater in New York City. The event, part of the annual meeting of the Association for the Scientific Study of Consciousness, featured an “adversarial collaboration” between proponents of the Integrated Information Theory (IIT) and the Global Neuronal Workspace Theory (GNWT).
The experiment, funded by the Templeton World Charity Foundation, aimed to determine whether consciousness arises from networks of neurons at the back of the brain (IIT) or within the brain’s prefrontal cortex (GNWT). Three neutral judges evaluated the results and gave a qualified victory to the IIT camp, suggesting that consciousness is indeed a feature of networks of neurons found at the back of the brain.
However, the GNWT camp is not ready to concede defeat. They argue that the experiment had limitations and that other tests in the adversarial collaboration will support the role of the prefrontal cortex. Stanislas Dehaene, the chief architect of GNWT, believes that the new findings do not confirm the specifics of IIT and that the results of future tests will provide a clearer picture.
The collaboration between the two camps was initiated in 2019 by cognitive neuroscientist Christof Koch and TWCF director Dawid Potgieter. The project aimed to test theories of consciousness and find a working theory that could have implications for various fields, including medical decision-making, animal rights, and artificial intelligence.
The first round of experiments involved scanning the brains of participants using various techniques. The results showed some support for IIT, with brain activity in the posterior regions correlating with conscious perception. However, there were also findings that aligned with GNWT, suggesting communication between visual and frontal zones during conscious perception.
Both theories have been widely discussed among researchers studying consciousness. GNWT gained initial support from experiments that focused on participants’ reports of awareness of stimuli, while IIT found support in “no-report” studies that monitored conscious perception independently of participants’ reports.
Despite the victory for IIT in the first round, the debate is far from over. The researchers plan to conduct further experiments to gather more evidence and refine their theories. The next experiment, funded by TWCF, will use a customized video game to isolate neural signals of conscious perception.
In the end, while IIT may have won the first round, Koch acknowledged the continuing doubts surrounding the results and paid off a 25-year-old bet to philosopher David Chalmers. He declared that he may have lost the battle but won the war for science.
The quest to understand consciousness remains a fascinating and complex endeavor, with researchers from various disciplines working together to unravel its mysteries.
